l Application tiled February 1'7, 1899. Serial No. 705,840. (No-model.)I

To ctZZ whom t 11i/(ty concern:

Be itknown that we, STEPHEN Il. GARS/r and DUDLEY GARsT, citizens oftheUnited States, residing at Detroit, inthe county of Wayne and State ofMichigan, have invented certain new and useful Improvements inCultivators, of which the following is a specification, reference beinghad therein 'to the accompanying drawings. y'

The invention has reference to riding-cultivators, and relatesparticularly to that class wherein the axles for the carrying-wheels areadapted to be shifted so that the said wheels may be inclined at will tothe'right or left,v

causing the machine to move at an angle to the linev of draft forth'epurpose'of more thoroughly cultivating the growing crop and to avoid anyirregularities or obstructions in the ground.

One of the objects of our invention is to.

' provide an improved shifting'mechanism for the axles adapted to carrythe driver and tol be operated by the latter from his seat, theconstruction of the mechanism being vsuch that the latter willvvalwaysbe inA parallelism to the wheels, whereby the driver willbe'constantly facing in the direction in which' the machine istraveling, and thus better enabled to control the movements ofY thecultivator.` Another object of our invention is to provide means wherebythe driver' may from his seat and by t-he use of a properYshiftingdevice move the plow-sections simultaneously either to or awayfrom each other and'to so form the shiftingdevicc that the latter vandthe plow-sections will operate insubstantially hereinafter described,andshown in the draw-l ings, `in which- .l ,v 1

Figure lisa plan View of a c ultivator, par-` tiall'yl broken away toillustrate some of the essential parts. v Fig. 2 is a longitudinal sec-vtion taken on line :c fc, Fig. l. Fig. 3 is a view the cultivator,consisting ofy a central crossbar a, front cross-bar l), the bars closetat an angle to each other, andbraces'cl, the parts being arranged asvshown in Fig'. l and secured to each other inany approved manner.

The central bar ct carriesy ldeper'niin'g therev from at each en d avbracket B, in which are v,')ournaled the pivoted; axles C, more fullyhereinafter described. A brace-rod e connects the lower end ofeachbracket to one of the bars c, vwhereby a rigid structure is obtainedwhich carries the movable` parts of the cultivator.

Fig. 4 is a sectional viewl f The axles C, just'referred to,arepreferably L- shape'd in conflguratiomcomprisingin their constructiontheaxlepropeijf, and the pivot -pin or bang, thelatter device beingadapted Vto engage .thebracket, as shown, and to. ex-

, tend 11p-and through thecentral cross-bar of -th'erigid'fra'me rlheaxles are retained with-l fin thebracketsby means of smaller brackets ,ny D, 'which engage the pinsbetween the crossbara and bearing t', formedon the brackets B, vandare iixedly secured to the pins by `snit` Thebrackets D, just described, comprise a rearu-'ardly-extendin g bodyportion E and forwardlyextending arms F, and to the 'body portion of thebrackets is secured a movable frame G, which Vconstitutes our limprovedshiftingdevice for the pivoted axles.' In con'n struction the frameconsists of side bars k and 'y a cross-bar Z, on which is mounted, atthe middle thereof, a seat H for the'driver.- The'sidey bars-are securedto the bracketsby bolts'm,

Fig. f2, which engage pairs of vertically-arranged apertures o withinthe bracket-body. This permits the frame to be adjusted vertically inthe brackets. By this construction of mechanism the operator is enabled,by pushing upon the plow-sections I, to shift the movable frame from oneside to another to ineline the wheels for the purpose before set` forth,leaving his hands free for driving and for operating the plow-sections.Likewise the driverbein g carried by the movable frame which isconstantly in parallelism with the wheels of the machine is alwaysfacing in the direction in which the wheels are moving, which enableshim to more effectively operate the cultivator.

The mechanism for spreading the plow-sections or forlmoving thelattercloser together is located upon the cross-bar J', which connectsthe free ends of the forwardly-extending arms F. In construction thismechanism comprises a gear-segment q, fixedly secured to the cross-barreferred to, and a shifting device in the form of a lever K, having apivotal connection therewith. This lever is provided with the usualspring-actuated latch r,

`the hand piece s for operating the same, and

two clips tu, Fig. 4:, which are swiveled thereto, as shown.

L designates theusual plow-beams, which have a pivotal connection withthe forward portion ofthe stationary frame A, and these carry theplow-sections I, before referred to,

saidsections each comprisingagroup of plows or a gang. Upon each sectionis located an upright'o, and a link w connects the upright with one ofthe clips upon the lever K. The Shifting lever extends rearwardly a sufticient distance, so that the driver is readily enabled to reach thesame from his seat on the movable frame, and by moving the lever thedriver actuates simultaneously the two plow-sections, bringing `themnearer together or spreading the same, according to the direction invwhich the shifting device is moved. served from this construction` thatthe uprights form the necessary arch for the cultivator, and byextending upwardly in the manner described and shownpermit theplow-sections to be more readily operated, as the line ofpull upon the plowt-sectionsis brought substantially in the same plane in which thehorizontal shifting lever operates.` t i It is frequently desired `toraise the plows partially out of the ground to lessen the depth of thecut or entirely from the ground during the operation of the cultivator;and to attain this object we employ the usual gear-segment andoperating-lever for raising the plow-sections, the segmentbeing'attached, as usual, to the stationary frame. The means we employ yfor locking the segment and lever, however, we believe to be entirelynew with `us, and the particular construction of saidlocking mechanismwill now be described. The reference-letter O designates the usualgear-segments,- which are ixedly secured to the inclined bars c of thestationary frame. Pivoted to the same bars in proximity to the Segmentsare the operating-levers P for the sections, each of which levers isconnected by a spring a; to the forward crossbar Z7 or any othersuitable part of the frame and by a-link M to the plow-section. Inconstruction each lever is preferably bifurcated, as shown in Fig. 5,comprising an outer membery and an inner member z, which embrace attheir lower ends the bar to which the lever is attached and arepivotally secured thereto by a pivotpin a';

In the lever members justreferred to, above the segment, are formedslots through which extends a latch b', said latch being pivotallyconnected to the membery by means of split pins c', engaging the latchupon opposite sides of the outer member. The latch just described isheld normally in engagement with the teeth of the segment by means of aspring d and is withdrawn from and vlocked out of said engagement bymeans of our improved locking mechanism, consisting, essentially, of aconnecting-rode' and a lockinglever Q.

More `particularly the construction of the locking device is as follows:The lever Q is pivoted, as shown in Figs. 5 and 6, to the inner membere' of the operating-'lever P and is quired distance and holds theplow-sections IOO in their raised positionsby allowing the latch l toagain engage with, the segment.

yWhenit is desired to allow the`plow-sections to rest upon the groundand to swing Vfreely,the,driver moves forwardly the locking-lever@ untilit passesover the dead-center, when furtherforward movement of the leveris checked by the stop g striking against the member y of the.` lever P.The latch is IIO `then locked in the desirediposijtion out of engagementlwith the segment;

`Vhat we claim` as ourl invention is- `l. In a cultivator, thecombination withthe stationary fram e, the pivotedaxles, arms projecting forwardly `from the axlesand a crossbar connecting the arms, amovable frame ex tending rearward `from said axlesuand controlling themovement of the latter,a seat upon said movable frame, the plow-sectionsy l pivoted to the stationary frame, `and counections between eachplow-.section and the cross-bar connectingthe fcrwardlyprojectingarms. nN -V 2.
